The knee is really just a hinge. It moves excessively (or not) based on your foot/ankle movement and your hip movements. This to really work on controlling what the knee joint does you need to work on lumbopelvic and hip/gluteal stability. And of course on ankle stability. Getting those as balanced as possible with give you more value to which you can then add various balancing exercises for the quads and hamstrings. Impossible to put it all into words on a forum but maybe going forward we'll have more video exercise ideas.
